SEAlVllNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 481,033, dated August 16, 1892.

Application tiled April 7,1892. Serial No. 428,194. (No model.)

To all whom it may concern:

Be it known that I, GOTTHILE F. E. KANZ- LEITER, a citizen of the United States, residing at Terre Haute, in the county of Vigo, State of Indiana, have invented certain new and useful Improvements in Seaming-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in seaming-machines, and more particularly to attachments therefor.

It has for its objects, among others, to provide a simple and cheap attachment which may be readily applied to any`seaming-machine now in use, and which will smooth down the seam after it is formed at'one and the same operation, avoiding the necessity of afterward hammering it down. I provide a spring-arm carrying a supplemental roller, and this arm is held against lateral movement by simple means. This supplemental roller travelsin the path of the seaming-roller and interferes in no wise with the successful operation of the other parts.

Other objects and advantages of the in vention will hereinafter appear, and the novel features thereof will be specifically den ed by the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form apart of this specification, and in which- Figure l is a side elevation of a portion of a seaming-machine, with a portion broken away, showing -my improvement applied. Fig. 2 is an enlarged perspective view of the parts constituting my invention detached.

Like letters of reference indicate like parts in both views where they occur.

Referring now to the details of the draw,- ings by letter, A designates a seaming-machine of known construction, B its rack-bar, C the crank, D the scanning-roller, and E the gear which actuates the rack -bar. All of these parts may be of any well known or preferred form of construction and operate in the usual Way.

My present invention consists in a supplemental roller F, which travels in close proximity to the seaming-roller and in the path thereof. This roller. is journaled in aspringarm Gr, which is held at one end in any suitable manner-as, forinstance, by a screw or bolt G passed through a hole g in the arm and into the under face of the rack-bar. This end of the spring-arm is slightly bent or curved, as seen in Fig. 2, to throw the other end slightly downward, and the free end is cut away to provide room for the roller F, as seen best in Fig. 2, the portions g upon each side ofthe said space being turned up and over to form the upper parts of the bearings for the pintlesf of the roller, as seen in both views, the under part of the said bearings being formed by l'lat springs H, which are attache-d at one end to the under side of the spring-arm G, and the free ends receiving the pintles, as shown. This permits of slight yielding of the roller, when necessary.

In order to prevent lateral movement of the spring-arm, and consequently its roller, I provide a means for engaging the sides of the rack-bar, and, as shown in Fig. 2, this means consists of a sheet-metal strip I, having its ends bent to embrace the spring-arm and a portion extending across the upper face of the said spring-arm and formed int-o lugs or ribs t', extending lengthwise of the spring-arm and adapted to snugly embrace the rack-bar,

and thuspermit of the necessary vertical play of the said arm and yet prevent any lateral movement thereof.

The advantages of such a construction and arrangement of parts will be readily understood. The seam is rolled down at one and the same time with the seaming thereof. No after hammering is necessary. It can be quickly applied to any and all seaming-machines of this character now in use and is a great labor-saver.

What I claim as new is A seamingmachine attachment consisting of a spring-arm having one end out away with" the side portions turned up and curved to form upper bearings for the pintles of a roller, a roller having pintles held in said bearings, springs secured to the under face of the spring-arm and receiving the pintles, and a plate with ribs upon the upper face of the said arm to prevent lateral movement thereof, in combination with the co-operating parts, as set forth.

In testimony whereof I aiix my signature in presence of two witnesses.

JAMES F. MURPHY, GEORGE GRIMES.
